Abstract

本发明公开了一种环保碱性液体肥料的生产方法,其特征在于,包括以下生产步骤:(1).取草木灰与水按重量比1:4的比例混合成浸液备用;(2).取松香磨成粉备用;(3).取废置食用油、松香粉、草木灰浸液按重量比1:1:5配比,搅拌混合,进行皂化反应,制得肥料。本发明制成的肥料,加水稀释后施撒于受重金属污染的酸性土壤中,可起到酸碱中和,降低镉等重金属污染的作用,降低阳光使土壤中水蒸汽蒸发带来的PM2.5的重金属污染颗粒,减少了毒素雾霾,使农作物获得丰收。

Description

环保碱性液体肥料的生产方法
技术领域
  本发明涉及的是农业领域,具体是一种环保碱性液体肥料的生产方法。
背景技术
土壤污染不是新话题,耕地尤其是重灾区。据悉,中国土壤水土流失,盐渍化、酸化等问题突出,耕地土壤环境质量堪忧,已经威胁到中国的粮食、食品以及饮用水安全等问题。此前就有媒体披露湖南等地出产的稻米被查出镉金属超标,“镉米危机”也存在多个省份。2015年国土资源部中国地质调查局公布的《中国耕地地球化学调查报告(2015)》显示,全国重金属中重度污染或超标的耕地占比2.5%,污染或超标耕地主要分布在南方的湘鄂皖赣区、闽粤琼和西南区。
土壤污染、酸化的原因还在于耕作方式。据统计,目前 全球每年进入土壤的镉总量为66万公斤左右,其中经施用化肥进入的比例高达55%左右。过往中国的粮食与耕地政策,强调耕地数量有限,提高总量和收入自然要提高亩产量。但农业生产技术的进步很慢,除了杂交水稻等跨越式提高亩产的技术以外,提高亩产主要靠劳动力、农药和化肥的掺入,这些都是以污染土壤和透支土壤肥力为代价的。据调查,与上世纪80年代的数据相比,东北黑土地有机质明显下降、耕地酸化趋势明显,东北地区耕地有机碳含量下降了21.90%,这主要是化肥过度使用和不采用一作一休(耕作一年,休耕一年)造成的。土壤污染说到底还是人的问题,要彻底有效地保护土壤也只能从降低土地上超标的酸性肥料,这只能在土壤中增加适量的碱性肥料,中和超量的酸性肥料,达到土壤的PH值平衡。
雾霾,是空气污染中的杀手。《全国土壤污染状况调查公报》作了最好的回答:农业污染超工业成我国最大面源污染产业。土壤污染空气,是造成雾霾原因之一。全国土壤状况总体不容乐观,部分地区土壤污染较重,耕地土壤点位超标率19.4%,主要污染物为鎘、镍、铜、砷、汞、铅、滴滴涕和多环芳烃等重金属污染。随着阳光使土壤中水蒸汽蒸发,带上了看不见的PM2.5的重金属污染颗粒,造成了毒素雾霾。
近年来,地沟油回流到人们餐桌的案例频频被新闻媒体曝光,让人们对地沟油深恶痛绝,任其排放到自然界中也是一种垃圾和污染物,对环境维护非常严重。
发明内容
本发明的目的是使用废置食用油(地沟油)皂化成碱性液体肥料,该肥料可作为调理剂使用,以减少土壤重金属污染及减少雾霾。
本发明环保碱性液体肥料的生产方法,其特征在于,包括以下生产步骤:
(1).取草木灰与水按重量比1:4的比例混合成浸液备用;
(2).取松香磨成粉备用;
(3).取废置食用油、松香粉、草木灰浸液按重量比1:1:5配比,搅拌混合,进行皂化反应,制得肥料。
本发明制成的肥料,加水稀释后施撒于受重金属污染的酸性土壤中,可起到酸碱中和,降低镉等重金属污染的作用,降低阳光使土壤中水蒸汽蒸发带来的PM2.5的重金属污染颗粒,减少了毒素雾霾,使农作物获得丰收。
具体实施方式
实施例:
环保碱性液体肥料的生产方法,包括以下生产步骤:
(1).取草木灰与水按重量比1:4的比例混合成浸液备用;
(2).取松香磨成粉备用;
(3).取废置食用油、松香粉、草木灰浸液按重量比1:1:5配比,搅拌混合,进行皂化反应,制得肥料。
